Abstract

The present invention relates to a method and arrangement for detecting a Region of Interest in an image data set, especially digitalized X-ray image. The method comprises the steps of: extracting phase information from the image data, using said phase information for differentiating between different lines and edges, and skewing said lines towards a centre.
